Described from living plants cultivated at Kesv and from living specimens sent 

 to Kew by Messrs. Galpui and Rattray, In the Kew Herbarium is preserved a 

 drawing of a branch (probably a rooted cutting) of this plant introduced by Bowie 

 in 1823, This drawing represents a very poor shrivelled and spineless branch, and 

 although doubtless the species, is e^'idently not the actual specimen, described by 

 Haworth, since he describes its spinea. Galpiri's 8101 is stouter than the other 

 living specimens seen, but is quite the same aa the Alicedale and Keimouth 

 plants.
